Responsible for generating adjustable analog speed setpoint for main regulator board.

Compatible with AutoMax control system for heavy industry production line.

Commonly used for old DC drive equipment maintenance and spare replacement.

Function

518491 is dedicated speed reference PCB board for RELIANCE CardPak DC drive system.

Provide local manual speed preset function via onboard potentiometer.

Generate stable analog reference signal and send to armature control board.

Built-in ramp circuit to realize smooth acceleration and deceleration adjustment.

Switch selection for local/remote speed reference mode switching.

Onboard test points for reference signal measurement and ramp time tuning.

Output speed command to closed-loop regulator circuit of DC drive.

Installation

Power off the whole CardPak drive rack and cut main power supply.

Insert 518491 board into designated slot of drive rack.

Fasten fixing screws.

Connect backplane edge connector and remote reference signal wiring.

Analog signal wiring adopt shielded cable and separate from high voltage power cable.

Power on system,calibrate speed preset value and acceleration/deceleration ramp.

Test local/remote switching and speed command stability.

Interface

CardPak backplane edge connector,remote reference signal terminal,local adjust potentiometer,mode select switch,test measurement points,status LED indicators.

Feature

RELIANCE 518491,CardPak speed reference printed circuit board.

Local manual speed setting and remote analog signal input selection.

Integrated acceleration and deceleration ramp shaping circuit to avoid shock load.

Potentiometer adjustment for flexible onsite speed calibration.

Standard CardPak plug-in structure,easy replacement.

Discontinued obsolete board,supply only for old automation drive system spare replacement.

Suitable for metallurgy,paper-making heavy-duty DC drive production line renovation.

Diagnostic

Speed reference drift:potentiometer aging or analog wiring interference;

No speed command output:backplane connector loose or board power fault;

Acceleration/deceleration abnormal:ramp circuit component drift;

Local/remote switching failure:mode select switch damage;

LED abnormal:board auxiliary power supply failure.

Product Brief
